Yeah the ROM on there is soldered on a lot of boards, it's right next to the SCSI connector.

It's socketed on this one (the AT27C256). Should be easy enough to find an EPROM version.

Of course you will need an EPROM programmer, UV eraser and the skills to build a custom ROM (which isn't that hard).

For the T-RexII ROM you don't need a UV eraser, just a programmer, and I have the patched ROM if someone wants it, but it's trivial to apply the patch.

Burning a custom Kickstart is a little more involved and I wouldn't recommend it unless you were doing it for other reasons.

I was assuming it would not work first time :-)

Can I get the patched ROM please?

Sorry, I had a look around and I don't know where I put it. It's really easy to do, just get the patch file from Doobrey and read the very short instructions.

Hi everyone, sorry I had to drop the Amiga 4000 project for a bit. Got my hands on a bunch of old computers, and had my hands full with a Comodore 64, an AT&T 286, and a Sun Ultra 10 for a while. Those projects are done - back to the holly grail of home computers.

Can someone help me with a patched rom for this card? I would rather pay someone to burn it for me, my time is a bit limited these days. My two kids are very demanding! If someone is willing to help me please message me with your email.

I can't wait to get the Amiga running on the compact flash!

I found the patched GVP Trexx-II ROM. There is an issue the fellow I helped out with this mentioned, with an IDE HDD+CDROM hooked up it would not boot. Or if he only had an IDE Drive hooked up set to Master (and I presume lastdrive flag set). I never saw any of these issues myself but maybe manually set your CF adapter to Master/Single, why Dynamic Computing said above.

The other thing once you get it to boot, is you can LoadModule PFS without the ROM update. What I was doing before was I had a small FFS drive on the IDE which would do all of my Loadmodule stuff, it would reboot then the now present GVP SCSI drive would boot.

Can anyone recommend hardware to burn this rom with? I want to get a known working solution.

Thanks.

Some CF cards are very picky. Make sure the CF card is on the Master Header of the IDE cable. Some CF cards will not work as a Slave & more so with a Master already in place.

& Make sure you have the 060.library in your Libs Drawer on the CF Drive before you boot from it.

Daedalus · 16 December 2018, 23:12

Indeed, and some CF cards won't even work as a master if there's a slave present on the cable.

Dangit, I knew I forgot to try something. Too many computers to fix. Rookie mistake. Will report back soon.

Hi everyone, I am sorry about not updating this.

I got rid of that blasted Sun machine and started playing and admiring the Amiga 4000.
I soon decided this was just too much Amiga for me. I was just not worthy.

What a machine, it just blew my socks off that it was introduced in 1992. I was 12 at the time and through much begging got my parents to purchase a Macintosh LC II. This was a toy compared to the Amiga 1200, not to mention this beast of a 4000. After playing with it a while, I decided this was not just a pile of PC parts. This was a little legend. It needed a proper care taker.

I sold it to a much more worthy enthusiast that worked on the machine in its hay day.

I built a small ITX x86 machine to run FS-UAE and have gotten it running pretty well. Not as great as the original hardware, but for a punk like me who grew up around early Macintosh computers, it will keep me very busy for a while. Very busy - until I feel like I am worthy of the A1200 I am lusting for. It's better this way, I have made virtual a virtual A1200, 4000 and loaded WB 3.1. Will experiment with an A500 and WB1.3 in the following weeks.

Mind has been blown. Considering I had no computer help in those days, I'm not sure if I could have wrapped my mind around an Amiga in 1992.
